Physical positions start at 1
Odd pages are 1,3,5… and even pages are 2,4,6…. Numbers printed inside sheets may differ when there is an unnumbered cover.
A seven-page document produces four odd and three even pages. A one-page document has no even group; an empty PDF is not created.
Separate and inspect
Choose both groups for a ZIP containing two PDFs, or odd/even only for a single output. Each group retains original order.
- Load the file and check its total.
- Select your group and process.
- Extract the ZIP if you downloaded both groups.
- Check each PDF’s first and last pages.
Manual double-sided printing
Separation cannot determine how to reload paper: printers differ in sides, trays and output direction. Test four pages and mark a corner before printing the full batch.
To alternate the groups again, use Interleave. For patterns other than parity, use Extract. Processing is local and supports up to 500 pages, subject to available memory.
